In 1998, bangladesh was affected by heavy floods. there were several reasons for the severe flooding. first, there were unusually heavy monsoon rains. that year, the himalayas also shed a lot of water. the heavy flow of water could not be blocked because of fewer trees. in the past, the trees kept the water from flooding. many of these trees had been cut for firewood or to make space for animals. such floods have now become a regular part of bangladesh's climate. this has also raised questions about bangladesh's future. some believe that bangladesh could be severely affected by climate change. rainfall has been increasing in the country. with climate change, the sea level is rising. tropical cyclones are also expected to increase. these dramatic changes will harm agriculture, safety of water and food, people's health, and shelter. to make things worse, most parts of bangladesh are less than 12 meters above sea level. if the sea level were to rise by a meter, half of the land would be flooded. which idea can be supported from the passage? a. climate is not changing in most asian countries. b. the world started changing rapidly since 1998. c. countries near the sea face numerous dangers. d. scientists have not studied flooding enough.
